Paradise wiped off the map

Ten search teams were working in and around Paradise — a town of 27,000 north of Sacramento. The town was almost completely burnt to ashes and more than 6,000 homes were completely destroyed. In this photo from Paradise, a staircase is the only thing left standing of what used to be a house.

Buildings burnt to the ground

The fires have destroyed thousands of homes, including several exclusive residences in Malibu, where many celebrities live. Actor Gerard Butler said on Instagram that his house in Malibu was "half-gone." At the People's Choice Awards on Sunday, stars called for prayers and donations to help residents and rescuers.

Escape from the fires

Evacuation orders have been issued for the entire town of Malibu. These horses have unusual temporary stables at the lifeguard towers on a beach in Malibu as a result of the Woolsey Fire. It's also affected the nearby town of Thousand Oaks, which was still reeling after a gunman killed 12 people in a bar on November 7.

Rescuers continue to work

Out-of-state fire crews continue to arrive in California, as winds and dry conditions are expected to fan the flames through the rest of the week. According to fire officials, by late Sunday the Camp Fire was around 25 percent contained, while only 15 percent of the Woolsey Fire was under control. California Governor Jerry Brown has declared a state of emergency.

Dealing with 'extraordinary' chaos

In explaining the massive jump in the number of missing, Butte County Sheriff Kory Honea told reporters that investigators raised the number after reviewing emergency calls made after the fire broke out last week.

"I want you to understand that the chaos we were dealing with was extraordinary," he said.

Deadliest blaze in state history: The "Camp Fire" blaze has so far destroyed 9,700 homes and displaced some 52,000 people. It devastated the town of Paradise, reducing many of the homes to ash and rubble. It is both the deadliest and most destructive fire in the western US state's history — more than doubling the death toll of a 1933 blaze in Los Angeles County that killed 29.

The Woolsey Fire, located north of Los Angeles, has killed at least three people and destroyed 500 structures. Scientists largely attribute the devastating blazes to climate change which has caused a prolonged drought in the state.

Trump to visit fire victims: US President Donald Trump will travel to California on Saturday to meet with people who have been impacted by the wildfires, the White House said in a statement. Trump sparked outrage over the weekend when he tweeted that the fires were to blame on state forest management and threatened to withhold federal funds.
